    Fixing cracked ABS plastic

    I use EMA Plastic Weld which I am pretty sure is also MEK based, and it works fantastically. I repaired a shattered front bezel of a 17" Multiple Scan, and most of the joins are barely visible from the outside. On the inside I stuck everything together with the Plastic Weld and then reinforced...

    What is the typical failure mode of resistor networks? (Dale 472G)

    While chasing scsi problems on my Quadra 800, I have determined that RP4, a Dale 472G (bussed, 4.7K) has some abnormal readings on a couple of it's legs, and those same legs do have continuity to the some legs 53C96 scsi controller (no extensive testing yet, not sure which legs specifically)...

    Advice for diagnosing scsi failure on Quadra 800?

    After a whole lot of messing around, including repairing two floppy drives and a not-booting G3 Minitower, and acquiring some actual floppy disks, I have an alternate boot method and an update. SCSI Probe says that the bus is not terminated. The Wombat board has active termination circuitry...

    Advice for diagnosing scsi failure on Quadra 800?

    An update: Thanks to member @trag I now have some brand new scsi IC's. Out of curiosity I was probing around the 53C96 with my scope and in the process it started booting from the internal scsi. I tried it a number of times without touching anything on the board and it booted normally every...

    What are your vintage grail items?

    One thing that's on my list and seemingly unobtanium is a working copy of MacBRAVO! by Schlumberger. It's pictured in the Quadra 700/900 brochure and I would absolutely love to have that running on my 700. As far as Macs go, an 840av is about the only remaining Mac that I really want. I still...

    Quadra PDS connector source?

    Yeah, here in the UK I only found them available on Mouser, also MOQ 200, £8.xx each. If it were me, I'd probably want to try and find one on ebay or something to check that it actually fits before I bought a load of them...

    Quadra PDS connector source?

    Can't confirm, but from the datasheet drawings 3M's PAK 50 connectors appear to be interchangeable with the KEL 8807. If you're able to confirm, you might be able to find those cheaper...

    Grateful to you - I did since find this listing on ebay for a more reasonable quantity, if it's a nuisance for you I'm happy enough to buy a lot of those. Let me know...

    Advice for diagnosing scsi failure on Quadra 800?

    Any hints or pointers gratefully received! Symptoms: Machine was working fine, I have been using it probably a few hours every other night over the last few weeks, booting from a SCSI2SD v6 attached to the internal scsi. Couple of days ago it started cold booting to the flashing ? disk, but...
